The prototype of fei cun Mark is the famous executioner Yan Zhai (1834- 187 1) on the river at the end of the curtain. This man is a vassal of Kumamoto, who actively advocates respecting the king and resisting foreign countries, resolutely opposes the "founding theory" and believes that Japan should continue to maintain its closed-door policy. In the first year of Yuan Zhi (1864), the famous great thinker Sasaki Xiangshan was assassinated. Sakuma was well versed in the art of war, and put forward "the use of military power" and "the theory of founding the country" long ago. Yoshida Shōin, a famous thinker, studied under him, which can be said to be the master of Takasugi Makoto and Kubo Junyi. It's a pity that such a wonderful person was assassinated by a conservative like Yan Zhai on the river. But on the other hand, because of this incident, Yan Zhai on the river gained great fame, so it can be said that it is a good thing to have a mark that is loved by all of us today.
